Abstract

A device for monitoring the temperature of a body, comprising a p-n junction (19) which is integrally packaged with a metal carrier (30) such as to be in good thermal contact therewith but electrically isolated therefrom. The p-n junction is provided by, for example, a triac, thyristor, power transistor or power diode. The metal carrier is adapted to be fitted in heat conductive engagement with a body whose temperature is to be monitored so that the p-n junction adopts rapidly the prevailing temperature of that body. A constant current supply (18) is connected to the p-n junction so as to pass a constant current therethrough, the voltage drop across the p-n junction being monitored as the temperature of the p-n junction varies in accordance with the temperature of the body. The magnitude of the voltage drop provides a measure of the temperature of the body.
